Efficient for searching	Efficient for insertions and deletions

2. What is Time Complexity?

Answer

Time Complexity measures how the execution time of an algorithm grows as the input size increases.

Examples:

O(1)  → Constant
O(log n) → Logarithmic
O(n) → Linear
O(n log n) → Linearithmic
O(n²) → Quadratic

3. Explain Stack and Queue

Stack

Follows:

LIFO
(Last In First Out)

Example:

Browser history
Undo operations

Queue

Follows:

FIFO
(First In First Out)

Example:

Ticket booking systems
Task scheduling

4. What is Object-Oriented Programming (OOP)?

Answer

OOP is a programming paradigm based on objects and classes.

Four pillars:

Encapsulation
Inheritance
Polymorphism
Abstraction

5. Difference Between Process and Thread

Process	Thread
Independent execution unit	Lightweight execution unit

Higher resource usage	Lower resource usage

SQL Interview Questions Asked in Zebra Technologies

SQL is frequently asked for Software Engineer, Data Analyst, and Data Science roles.

1. What is a Primary Key?

Answer

A Primary Key uniquely identifies each record in a table.

Name VARCHAR(50)
);

2. Difference Between DELETE, TRUNCATE, and DROP

DELETE	TRUNCATE	DROP
Removes rows	Removes all rows	Removes table
Can use WHERE clause	Cannot use WHERE	Deletes entire structure
Can rollback	Usually faster	Removes schema

3. What is an INNER JOIN?

Answer

INNER JOIN returns matching records from both tables.

Example:

FROM Students
INNER JOIN Courses
ON Students.ID = Courses.ID;

4. Explain Normalization

Normalization organizes data to reduce redundancy and improve consistency.

Common forms:

1NF
2NF
3NF
BCNF

5. What is the Difference Between WHERE and HAVING?

WHERE	HAVING
Filters rows	Filters groups
Used before grouping	Used after GROUP BY

Example:

SELECT Department,
COUNT(*)
FROM Employees
GROUP BY Department
HAVING COUNT(*) > 5;
